I simplified the code, by removing the variable snet_num_listeners and
use the value of snet_nl_pid
 * if snet_nl_pid == 0, then there is no userspace listening application 
 * if snet_nl_pid > 0, then its value is the PID of the listening
   application

In the same time, I deleted the check on a listener for this operations
on verdict : snet_nl_version, snet_nl_insert, snet_nl_remove,
snet_nl_flush, snet_nl_verdict_delay. 
In this way, it's possible to execute this operations and get events in
the same time (which means have a listeners)

Patrick, thanks again for reviewing
